Embodiment Construction

[0033]While this invention is susceptible of embodiment in many different forms, there is shown in the drawings, and will be described herein in detail, specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the specific embodiments illustrated.

[0034]FIGS. 1 and 2 show a container system 10 having a closure assembly 12 and a container 14. The closure assembly includes a one-way valve that allows for evacuation of fluid from the container but does not allow a significant quantity of fluid to enter the container through the assembly 12. In one preferred form of the invention, the container 14 is capable of being opened and closed repeatedly without the use of a tool or heat source by utilizing a zipper 16 or other member for sealing an end of the container. FIG. 2 shows the container in an unsealed position with an opening 18 at an end of ...

Abstract

The present invention provides a one way valve having a valve body, a wall, a fluid inlet, and a fluid outlet. The valve has a plunger which is moveable with respect to the valve body from a first position to a second position. The valve also has a diaphragm positioned in the valve body for movement between a third position and a fourth position when the plunger is in the first position. When the diaphragm is in the third position the fluid outlet is closed and when the diaphragm is in the fourth position the fluid outlet is open.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This is a continuation-in-part of U.S. patent application Ser. No. 11 / 020,380, filed Dec. 22, 2004, now U.S. Pat. No. 7,398,953 which is incorporated herein by reference and made a part hereof.FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not Applicable.BACKGROUND OF THE INVENTION[0003]1. Technical Field[0004]The present invention relates to a container system for storing articles in a reduced air environment.[0005]2. Background Art[0006]Collapsible, evacuable storage containers typically include a flexible, fluid-tight bag, an opening through which to place an article in the bag, and a fixture through which to evacuate excess air. A user places an article into the enclosure through the opening, seals the opening, and then evacuates the fluid through the fixture. With the chamber thus evacuated, the article contained therein may be significantly compressed, so that it is easier to transport and requires substantially less storage space....
